Chromium Potassium Sulfate Dodecahydrate from Germany
This double salt, KCr(SO4)2·12H2O, is a chrome alum used in analytical chemistry and trivalent chromium plating baths. It qualifies under HTS 2833.29.40.00 as a sulfate of chromium, though borderline with 2842 for complex salts. Its violet crystals are standard in lab reagents.

Import Tips
• Provide crystallographic data or formula confirmation to distinguish from true double salts in 2842
• For lab imports, include end-use statements to avoid industrial chemical scrutiny
